Indiana University - Indiana Geological & Water Survey
||Some IGS geologists, academia, government employees, geologic consultants, and the general public need to know where industrial mineral producing sites are and how to contact them.
||To produce a database of industrial minerals mines in the state and keep it up to date on a quarterly basis.
||Start with known operations. Check activity against Mine Safety and Health Administration records, Indiana Mineral Aggregates Association records, Business Division of the Indiana Secretary of State, and other public records. Also check those records for new operations. Make phone calls to companies for which public information is not available, or is unclear.
||A database of active industrial mineral producers to be published on the IGS Website.
||Geologists, and others, will know where active mines are and how to contact them. The location information will be used eventually to update the layer of active mines in IndianaMap.
